Description

Technical Field

[0001] The utility model relates to the field of power regulator installation, in particular to a drawer-type module cabinet for temperature-controlled thyristors. Background Art

[0002] Thyristor is a four-layer PNPN structure device composed of PNP junction and NPN junction. The work of thyristor is to control the current added to the trigger pole to control the conduction or medium of the entire device. The conduction characteristic of thyristor can switch a small current to obtain a large current output. Thyristor is mainly used in temperature control of heating equipment, and the purpose of temperature control is achieved by adjusting the current size. Therefore, thyristor is one of the important components of power regulator.

[0003] Existing power regulators are generally wall-mounted, and during installation, the power regulator is fixed to the component board in the cabinet by bolts. If a problem occurs and maintenance is required for the power regulator installed in this way, the power must be turned off to operate, and it cannot be used in situations where the machine is shut down or production needs to be quickly resumed. Utility Model Content

[0004] The utility model aims to solve the problems in the background technology and provides a drawer-type module cabinet for temperature-controlled thyristors.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A drawer-type module cabinet for temperature-controlled thyristors comprises a cabinet body, support columns, drawers and a power regulator module, wherein three rows of support columns are arranged in the middle and on both sides of the cabinet body, two rows of horizontally arranged multi-layer drawers are installed between the three rows of support columns, two groups of parallel power regulator modules are installed in each drawer, and the power regulator modules are installed with hot-swappable terminals, a plurality of positioning holes are evenly processed on the support columns along the vertical direction, symmetrical cabinet doors are arranged on the front side of the cabinet body, a line entry space is reserved in the cabinet body at one end of the drawer away from the cabinet door, and a heat dissipation hole plate is installed on the cabinet body at one side of the line entry space away from the drawer.

[0007] The line inlet space is provided with a copper busbar tube connected to the outside.

[0008] There are lifting rings installed at the four corners of the cabinet top.

[0009] The drawer-type module cabinet for temperature-controlled thyristors provided by the utility model has the beneficial effect of: by installing multiple drawers on the cabinet body and installing two groups of power regulator modules in each drawer, the on-site installation space can be saved to the maximum extent; at the same time, the power regulator module adopts hot-swappable terminals, which can be plugged in and out with power on, thereby realizing rapid change of the power regulator and greatly improving maintenance efficiency.

[0016] Example

[0017] like Figure 1 to Figure 4 As shown, the drawer-type module cabinet for temperature-controlled thyristors provided in this embodiment includes a cabinet 1, support columns 2, drawers 3 and power regulator modules 4. Three rows of support columns 2 are arranged in the middle and on both sides of the cabinet 1. Two rows of multi-layer drawers 3 are installed horizontally between the three rows of support columns 2. Two groups of parallel power regulator modules 4 are installed in each drawer 3. The power regulator modules 4 in each drawer 3 work independently. The two groups of power regulator modules 4 in each drawer 3 are used one for use and the other for backup. Both groups of power regulator modules 4 are installed with hot-swappable terminals. The hot-swappable terminals can be plugged in and out with power on and quickly changed, so that production can be restored within a very short dead time, which can effectively improve maintenance efficiency. The support columns 2 are evenly processed with multiple positioning holes 5 in the vertical direction. Symmetrical cabinet doors are arranged on the front side of the cabinet 1. A line entry space 6 is reserved in the cabinet 1 at one end of the drawer 3 away from the cabinet door. The line entry space 6 is used as a wiring terminal for multiple groups of power regulators. A heat dissipation hole plate 7 is installed on the cabinet 1 at the side of the line entry space 6 away from the drawer 3.

[0018] In order to facilitate wiring, the incoming line space 6 is provided with a copper busbar 8 connected to the outside. The copper busbar 8 has high stability. Once the power regulator fails and needs maintenance, production can be restored in a very short time with the hot-swappable terminals.

[0019] In order to facilitate the installation of the cabinet 1 , hanging rings 9 are installed at the four corners of the top of the cabinet 1 .

[0020] The method of using the utility model is:

[0021] When a problem occurs, the drawer 3 can be quickly opened by pulling, and then the hot-swappable terminal can be unplugged and connected to another power regulator module 4 to eliminate the fault. At this time, production can be quickly resumed, and then the staff can replace the faulty power regulator module 4.

[0022] One cabinet can be installed with 18 drawers 3, each drawer 3 can be installed with 2 sets of power regulator modules 4, and a total of 36 power regulator modules 4 can be installed, which can save the installation space on site to the maximum extent.

[0023] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and the utility model concept provided by the present invention shall be included in the protection scope of the present invention. It should be noted that the structures or components illustrated in the drawings are not necessarily drawn to scale, and the present invention omits the description of known components and processing technologies and processes to avoid unnecessary limitations on the present invention.
